The paper shows the mechanism and kinetics of the formation of diffusion coatings deposited in the medium of low-melting liquid metal melts depend on the nature of the interaction of the elements forming the coatings with the elements of the coated steel. When applying a coating based on Ni-Cu, the following features were revealed: the presence of a process of carbon displacement by the coating elements deep into the coated material; the practical absence of the influence of the carbon concentration in steel on the coating formation process; the elements of the coated material that do not interact with the coating elements are pushed deep into the product. The paper presents a scheme for the formation of diffusion coatings. Formulas for calculating the diffusion fluxes and the coating thickness are presented.
